GLASSWOBKING MACHINE.

Application filed March 24., 1921. Serial No: 455,026.

To all whom it may concern."

Be it known that I, Tmsononn H. SLOAN,

a citizen of the United States, and a resident of Charleroi, in the county of l/Vashington and State of Pennsylvania, have invented a new and useful Improvement in Glassworking Machines, of which the following is a specification.

The invention relates to apparatus ahd 1 machines for finishing glass articles in a heated condition, andis particularly applicable to machines for crimping the upper 'ends of lamp chimneys after they have passed through a heating furnace.

The object of the invention is to provide a glass-finishing apparatus in which the fin ishing tool is moved to and from its operative position in dependable coordination with the movement of a conveyor for'carrying articles through a heating furnace so that the tool will be brought into proper registrywith each article carried by the conveyor.

A further object is to provide a glass-finishing machine having an article positioner which engages and positions the articlewith relation to the finishing tool before the article is engaged by the tool, and which holds the article until after the tool has become disengaged from it.

A still further object is to provide a glass finishing machine, the operating parts '0 which may be adjusted tofinish glass articles of yarious sizes.

The invention is illustrated in the accompanying sheets of drawings in its applicability to apparatus for crimping the upper end of lamp chimneys. Fig. 1 is a somewhat diagrammatic plan View of the end of a heating furnace and a portion of a conveyor for carrying chimneys through the furnace,,a crimping machine being indicated adjacent to the end of the furnace; Fig. 2 is a side elevation to enlarged scale of the crimping machine, the plane of view being indicated by the line IIII, Fig. 1; Fig. 3 a right end view of the machine as seen in Fig. 2; Fig. 4 a horizontal sectional View taken on the line IVTV, Fig. 2; Fig. 5 a vertical central sectional view to enlarged scale of the crimping tool and article-positioner, the

lane of view being indicated by the line -V, Fig. 4.; and Fig. 6 a fragmentary perspective view of the moving parts and drivingconnections of the machine.

i In the practice of the invention, glass articles such as lamp chimneys, are carried through a suitable heating furnace 1 by. means of a conveyor which is preferably of the continuous type comprising a pair 0 sprocket chains 2 having supporting plates 3 extending between and attached to them at definite positions with relation to the links of the chains. The plates are provided with or shaped to form cups or saddles'4 for loosely supporting the glass articles. When the apparatus is used for crimping the tops of lamp chimneys, the saddles 4 are provided with central openings so that the lower ends of the chimneys are exposed to the heat below the conveyor, andthe furnace is constructed to heat both ends of the chimneys. The heating of the lower ends is for the purpose of fire. finishing their rough and and the heating of the upper sharp edges,

glass that it may be ends is to so soften the fee readily shaped by the. crimper located at the end of thefurnace.

The glass-finishing machine in its preferred form comprises. a frame provided with a carrier which is movable to and fro parallel to the conveyor and in line of its advance. Borne by the carrier, there is a finishing tool mounted for reciprocatory movement toward and from the conveyor. Separate'connections are provided between t the conveyor and the carrier and tool for coordinately efi'ecting their movements in both directions and at the proper times with relation to the advance of the conveyor. These connections, as well as the support for the carrier. are provided with suitable adjustments so that the carrier may be positioned, and the tool properly operated, at any desired distance from the conveyor, the distance depending upon the size of the articles being finished. The machine also includes an article-positioner which successively engages and brings the articles, carried loosely in the saddles of the conveyor, to the proper position with relation to the tool before the tool is moved into engagement with the article, and which also holds each engaged article upon the conveyor until after the tool has been disengaged from the article. Having referencenow to the chimney crimper which is the embodiment of the invention illustrated in the. drawings, all the conveyor. On the upper portion of the frame a support for the crimper carrier is i I mounted for vertical adjustment. This support comprises a horizontal bar 6 attached to a block 7 which is connected to a small housing 8 by means of bolts 9 extending through a slot 10 formed in the frame. The face of the frame is provided with a rack 11 with which there meshes a pinion 12 mounted on a small shaft 13, which shaft is rotatably mounted in the housing 8 and is provided at its outer end with an operating handle 14. By loosening the bolts 9, the handle 14 may be turned to .move the carrier support upwardly or downwardly to the required )osition, and when in such position the olts may be again tightened.

, The crimper carrier. indicated at 15, is slidably mounted upon bar 6, and is provided on its side with a socket 16 engaged by the outer end of an oscillating arm 17 secured to a vertical shaft 18. This shaft is rotatab-ly mounted at its opposite ends in brackets 19 and 20 forming parts of the machine frame, and is provided with a collar 21' bearing upon the upper edge of bracket 20 to hold the shaft in its vertical osition. To the lower end of shaft 18, there 15 attached an arm 22 provided with a projection in the form of a roller 23 extending into a cam slot 24 so formed in the periphery of a drum 25 that as the drum rotates the arm will be oscillated. For rotating the drum 25 in positive and certain coordination with the advance of the conveyor, the drum is mounted upon a. shaft 26 provided with a sprocket wheel 27 which is engaged and rotated by the sprocket chain of the conveyor. By attaching the conveyor supports 3 with their saddles 4 at regular intervals to the links of the sprocket chain, the cam drum 25 may be so rotated that the crimper carrier properly advances in registry with each support. The cam slot 24 and the lengths of the oscillating arms 17 and 22 are so proportioned that the forward movement of the crimper. carrier is at the same rate of speed as that of the advancing conveyor, and so that there is a quick return of the carrier. For adjustingthe driving connections of the crimper carrier, the arm 17 is slidably mounted on a. squared section of shaft 18, and is clamped thereto by means of a yoke 28.

The crimping'tool 29, which may be of familiar or any desired construction, is attached to the lower end of a rod 30 mounted for vertical reciprocation in the outer end of carrier 15. Rod 30 is preferably recipro-- cated by connections extending from a cam 31 mounted on shaft 26 adjacent to drum 25.

' The driving connections include a bell crank lever, pivoted at'32, to the machine frame, and having an arm-33 bearing upon cam 31 and an arm 34 adjustably attached to a rod'.

35 by means of a set screw 36 having an operating handle 37. For holding the arm 33 upon or toward the face of cam 31, the bell crank lever is provided with a. projection 38 to which there is attached a spring 39 adjustab'ly anchored to the machine frame by means of a pin 40. To shaft 35 there is attached, by means of a. universal joint 41, the lower end of a shaft 42, the upper end of which is attached by a similar joint to one end of a rocking arm 43. The other end of arm 43 is attached to rod 30 by means of a link 45, universal pivot joints 46 and 47 eing used to make the connections. Rocking arm 43 is pivoted at 48 to the upper end of a bracket 49 supported by the vertically adjustable block 7 of the carrier support, so

that but a single operation is necessary for borne by the tool carrier and is so con- I structed that it is normally urged toward chimney-engaging position and is moved from such position by the upward movement of'the crimper after the crimper has moved from a. chimney. The positioner preferably comprises a pair of arms 50 pivotally suspended as at 51 from the upper portion of the crimper carrier, each arm being provided at its lower end with apair of fingers 52. Each finger is clamped to the arm 50 by means of a screw 53 and may be independently adjusted toward and from the center line of the crimper. That the two positioning arms may swing simultaneously to and from chimney-engaging position, they are provided with laterally extending fingers 54, the outer ends of which areprovided with teeth 55 forming segmental pinions which mesh with each other inthe line of reciprocation of the crimper. These fingers extend into a slot 66 formed in the crimper-supporting rod 30.

By suspending the arms 50in the manner shown, they are normally urged by gravity toward chimney-engaging osition. preferably, however, springs 51- Fig. 4) are provided to urge the arms inwardly. To move the arms outwardly upon the upward movement of the crimper, each ma be provided with a plate 56 having a have ed edge lying in the path of movement of the upper po1'-.

tion of the crimper. The arrangement is such that the crimper rises from a chimney before itstrikes the plates 56, and hence the positioning arms remain in chimney-engaging position until after the crimper has been disengaged from a chimney.

The machine includes means for lubricating the bearing parts of the tool carrier and the crimper rod 30, ,and also for feeding oil to the crimping tool. For this purpose an oil cup 57 is mounted upon a bracket 58 carried by the vertically adjustable bracket 49. A tube 59 leads downwardly from the cup to a trough 60 attached to the crimper carrier so that oil may flow upon bar 6 to afford lubricationfor the-crimper carrier, md upon rod to lubricate its bearing within the tool carrier. Sufficient lubricating oil is caused to flow that some ofnit runs down the rod 30 upon the top of the crimper, which is rovided with vertical ducts 61 through wiiich the oil flows upon the crimping surface. he operation of the machine will no be explained. Before setting the machine in operation, it is adjusted to the size of chimneys which it is desired to crimp. The crimper-carrier support adjustment is effected by loosening the bolts 9 and turning the small shaft 8 until the support 6, 7 is in its desired position, after which the bolts are tightened. This adjustment also positions the rocking arm 43 which is pivoted to bracket 49 supported by block 7 of the carrier support. Arm 17 is then vertically adjusted upon shaft 18 so that its end is engaged by socket 16 of the crimper carrier. The connection of shaft to bell crank lever arm 34 may then be adjusted in proportion to the two previously mentioned ad justments so that the crimper will be in its proper position with relation to the chim nevs.

The apparatus being thus adjusted, chimneys are placed loosely upon the saddles 4 of the conveyor as they enter the furnace, and the conveyor is caused to travel at such speed as may be necessary to have the chimneys properly heated as they emeree from' the furnace. The crimper carrier is recipro-- cated parallel to and in the line of movement of the-conveyor, the driving connections being fromone of the sprocket chains of the conveyor through sprocket wheel 27, cam drum 25, arm 22, shaft 18 and. arm 17 which engages the crimper carrier. Simultaneously with the forward and backward reciprocation of the crimper carrier, the crimper is vertically reciprocated, the driving connections being through shaft 21, cam 31, bell crank lever 33, 34, rods 35 and 42, rocking arm 43, link 46 and rod 30. The universal joints 46 and 47 at the ends of link 45 permit of the crimper rod 30 to be horizontally reciprocatcd by the crimper carrier while the rod is being moved vertically. When a chimney moves to its position beneath the crimper, the chimney-engaging arms 50 are held outwardly by'the crimper which is then in its upward position. moves downwardly the arms 50 gradually swing toward the chimney and engage it before the crimper reaches its top. Thus,

As the crimper I the positioningarms bring the chimney to,

and hold it in, the position required for the proper functioning of the crimper. Near the endof the forward movement of the carrier, the crimper is caused to rise from the chimney and becomes disengaged there from before the crimper strikesthe plates 56 of the chimney-engaging arms 50 and moves the arms from chimney-engaging position. By reason of this operation, thechimney may not be moved from its support in case tlf e crimper should happen to stick to the top 0 it.

The crimping machine has-been found to be very effective in operation. The chimneys are properly crimped regardless of the small variations usually incident to the conditions of operations, such variations being in the thickness of the glass,'in the lengths of the chimneys, and in the degrees of plasticity to which the glass is brought by reason what I now c-onsider'to be the best embodiment thereof. However, I desire to have it understood that, within the scope of the appended claims, the invention may be practiced by other formsof construction, and by machines embodying other details of construction, than that specifically shown and described herein.
